Wire Chart Says 12AWG Wire is not good for my 100A ESC and LiPo

Here is a look as to how wire within a battery, ESC or Motor can be as small as they are and still pass current through them. When we are talking about 100 Amps going through these wires, it's a true 100A.
Note: The LiPo in this example uses 10AWG wire, but for simplicity of the example, we stick to 12AWG.

Great video! I always wondered how RC manufacturers managed to use such high wire gauges to carry seemingly absurd amounts of current compared to the wires inside the walls. Now it all makes sense. Household wiring is long, has no airflow, has to be efficient, can't be a fire hazard because its surrounded by flammable material, has no limits on how long high current can flow through it, vs a lipo that will die in a few minutes at high current, and has to work unsupervised for decades.

You got it!

@mossyhollow3732 2 года назад

Usually we won't be loading the motor/ESC to those max capacity amps for more than a few moments anyway. Great topic!

@RCexplained 2 года назад

Absolutely, this is part of the equation to identify what wire gauge is suitable.

Good video Ryan! I’ve had to explain this to a few people now with the generators I’m building. Thanks for putting it all in a nice and easy to understand format!

@RCexplained 2 года назад

Glad to help!

@remkojerphanion4686 2 года назад

Great stuff Ryan. I have often wondered why some ESC's and motor wires seem so thin!

@JakeItsTheCops Год назад

Awesome video! Very informative. I liked how in-depth you got with the math behind it.

@RCexplained Год назад

Awesome, thank you!

@tomfalls1006 2 года назад

Thank you! I’ve been referring to the AWG charts for wire size and could not figure out the discrepancy. Problem solved!!

@RCexplained 2 года назад

Glad I could help!

@derricksazrc3411 2 года назад

Your info was very enlightening. I’m building an EDF boosted Midnight Pumpkin Drag Truck and and I’m trying to figure the best position for the wires and batteries that will also cool everything at the same time. I know now that it’s a bad idea to elongate the wires eh.

@hifinsword 2 года назад

That was a good video b/c it's right up my alley with the EDFs I fly. Maybe a video using a watt meter showing the actual voltages, amps and watts generated, i.e. static thrust test, would be a good project to compare theoretical vs actual. A heat meter would also be used to see what heat is produced. I've found that 10AWG is about the limit for wires to be used in order to bend enough for practical use. But lower gauge wire, bigger diameters could be used if specifically designed so that they plug in without any twisting or bending during the build. But the odds of getting the CG right on with the battery pre-placed would be difficult.

If you don't want the 32W of heat in 24 inches of wire, then get rid of the WIRE!!!! Shorten the connection to near nothing, with the leads cut to 1/2" or less into the connector on BOTH devices, and presto, the losses magically disappear. 😁😁👍👍👍

@carscoffee5263 2 года назад

You’re right it wouldn’t be practical to try and solder 6awg wires to power systems ourselves. Trying to manipulate thick wires can ruin a day 😂 I installed a 120mm 12v computer hard drive fan to my rc car shell to help heat dissipation that blows air on my battery,esc,motor simultaneously.

@CharlieSolis 2 года назад

Ryan, question! Is it super important to use electrical flux when doing high power wire soldering?

@bigboytoyzrc9258 2 года назад

I don't think Ryan ever answer questions? Lol At least he never answers mine🤣🤔

@RCexplained 2 года назад

Charlie, I use flux everywhere I can as it just makes it easier to get a good solder done quickly. Everything Tech! Rc & Dronez, I don't always see every question. Best place for questions is Patreon as I see all questions asked.

@2testtest2 2 года назад

The only important thing is that you get a good solder joint. Using sufficient quantities of the right kind of flux is very much part of that. If your solder does not wet the surfaces properly, but want to bead on top of them, or form "buggers" or a matte wrinkly finish on the surface, then you need more flux. Otherwise you should be fine.

So can I run 14ga wire on a 1/10 truggy on 2s with a 5700 motor? Thank you so much!

@rcmod642 2 года назад

Great video!! thank you

Nice video, thanks:)

@coolsly64 Год назад

I have a question on my proboat Veles 29 the dynamite 120a ESC has very short amount of wire and it is set up in series and the ESC cuts out at high speed on my big 6s set up now my 2 thoughts are could I be pushing the ESC to hard or can I make it work wit some modifications like it has standard 5.5mm bullets on the ESC to the motor I was thinking of upgrading them to 6mm as well as a slightly longer more traditional length wires to batteries to reduce heat and ware do u think this will help this ESC at all or should I just upgrade the ESC?

@RCexplained Год назад

Make sure your batteries can handle the load and you are not entering low voltage cutoff. The shorter your wires are, the better. Changing plugs, won't do much for you.

@coolsly64 Год назад

@@RCexplained ok I'll check and make sure it's not going into low voltage cut off

@bigboytoyzrc9258 2 года назад

Thanks man I was wondering why my resistance on my 7500 100c gensace batteries read 4,2,11 and there brand new. Is 8g wire ok and how much resistance in comparison to the 12g? I'm running 1717 1650kv Xlx2 on infraction 8s

@paulclancy2404 2 года назад

I wanted that set up , I put rebranding hw from team coralley , with 27t pinion and ran like a champ something about that setup compared to a typical rtr 2050 , I do have 3 high-power fans , the less wire you have the better and less heat buildup less resistance just like sometimes open throttle is better less heat than half throttle, trick with infraction is high c rating batts and good cooling 😎

@RCexplained 2 года назад

The resistance on your LiPo battery is mainly coming from the chemical resistance within the cells. 8AWG will have about 2.5x less resistance

@twilliamrc4wd 2 года назад

you are basing of AC current charts and DC current silicone wires are different I have more strands they can handle more current so if you look online a standard 10 gauge silicone wire can handle close to 270 amps

@jozimoto 2 года назад

Consider that large gauge wire could be as large or larger than some of the actual components used.

@paulclancy2404 2 года назад

Is there a way to measure amp draw on a rc motor or a way telling if the motor is not running as efficiently as new , I have a few same motors and seems like some run hotter , ive changed the bearings and sometimes the rear bearing could be froze without knowing , ps seems like they really cheap out on lipo battery wires , I would rather pay few more bucks for copper or even just heavier gage

@rcyalater...2305 2 года назад

I'm sure it would be a pain but you could always DIY your lipos. Ya know with extreme caution

@RCexplained 2 года назад

Hi Paul I would data log the runs that you make with the only thing being changed out is the motor. If this is an RC Car - It would be easiest but perhaps not practical for you to see the difference on a bench test using a propeller as the load.

@nothingpromised2569 2 года назад

30 watts isnt that much ... ??? about the same as my soldering iron wish they would spend a bit more on manufacturing !

@paulclancy2404 2 года назад

Me too they really have it down to science using least as possible, sometimes im amazed how much power through these cheesy wires they aluminum too probably less resistance but very soft and dangerous compared
